Overview by GAK

2-IN/4-OUT USB Audio Interface

The SSL 2+ features the same amazing spec as the SSL 2 and expands upon its connectivity with: an additional headphone port with its own level/mix controls, MIDI I/O and two sets of phono outputs.

The SSL (Solid State Logic) name is associated with incredible quality and a storied legacy, with their consoles featuring on hit records by legendary artists such as Nirvana, Nine Inch Nails, Aerosmith, AC/DC, Bruce Springsteen, 2Pac and countless others. With their SSL 2 and 2+, SSL have imbued their supreme knowledge and signature sound into an affordable, intuitive USB interface. Now, you can harness the classic SSL sound for your own recordings! You’re not just paying for the name, you’re receiving a well-designed and fully-featured interface that stands out from the stiff competition.

At the core of the SSL 2/2+ is their gorgeous SSL-crafted microphone preamps, which boast pristine 24/192kHz conversion. The use of high-quality components is reflected in the clarity of tone and lack of noise that you hear as soon as you record with it. Thanks to the SSL 2/2+’s crystal-clear monitoring paths and top-performance headphone amps, you’re guaranteed a detailed and honest playback experience.

The SSL 2/2+’s interface boasts an intelligent design that isn’t overcomplicated. All the controls, like the huge Monitor Level knob, are right where you need them so your workflow isn’t interrupted. It’s visual and hands-on if you need to make adjustments on-the-fly, no menu diving required to achieve a great sound. It also runs off of USB power so all you need to do is plug it in and start making your hit record!

The not-so-secret weapon of the SSL 2/2+ is the “Legacy 4K” mode. Inspired by the mythical SSL 4000 console, pressing the 4K button instantly adds lush analog mojo and a musical high-end shimmer to your vocals and instruments.

The icing on the cake is the free “SSL Production Pack”, which provides you with a fantastic toolbox of software that works in tandem with the interface:

  • SSL Native™ Vocalstrip 2 & Drumstrip plug-ins + an extended trial of the complete suite

  • Native Instruments® Hybrid Keys & Komplete Start

  • Avid®Pro Tools® | First + an exclusive SSL collection of AAX plug-ins

  • Ableton®Live Lite™

  • 1.5GB Samples from Loopcloud®

For a limited time (1/11/20 - 31/12/20), Studio State Logic is expanding the Production Pack to include two additional SSL plugins - FlexVerb and X-Comp! This promotional offer applies to new customers and existing customers.

If you require MIDI connectivity, an extra headphone output with its own level/mix controls and phono outputs - check out the SSL 2+. Apart from the extra ports, the 2 and the 2+ feature an identical spec!

Overview by SSL

Legacy 4K – Analogue Enhancement

Real analogue enhancement inspired by SSL 4000 series (4K) console:

SSL has a history of innovation in analogue electronics and console design. Whether it be the sound of our classic EQ ‘242’ and ‘292’ EQ circuits, the punch of the legendary SSL G-Series Bus Compressor or the incredible bandwidth and sonic accuracy of our ground-breaking SuperAnalogue designed mic amps and consoles, we’re always moving forward with analogue.

Legacy 4K is an all-new analogue enhancement effect, inspired by the character of an SSL 4000 series console (often referred to as ‘4K’). With the Legacy 4K button, we’ve distilled 2 essential characteristics of the 4K sound into a single-circuit, which you can engage when you need to breath some life into ‘boring’ or ‘dull’ sounding input sources.

1st characteristic: High-Frequency EQ boost – The first thing engaging the Legacy 4K button will do is introduce a ‘forward’, yet musical high-frequency EQ boost, something which 4000-series EQs are known and loved for.

2nd characteristic: Subtle-Harmonic Distortion – 4K consoles are synonymous with imparting a certain ‘mojo’ to signals passing through them. This mojo comes through multiple stages of harmonic distortion from compressor VCAs, VCA Faders and other crucial areas like the transistor mix amps. Using modern components, we’ve created a circuit that injects a controlled amount of finely-tuned, sweet-sounding harmonic distortion into the signal path, helping to give your sound more edge!

Professional Studio Quality, Front To Back

Class-Leading Preamps:

The Art: We’ve designed 2 class-leading, beautifully detailed mic preamps to capture every nuance of every performance, with enough gain to cope with whatever microphone you’re plugging in.

The Tech: Many USB-powered audio interfaces use standard IC circuits in their mic amp designs. We prefer to use a different approach. Our 2-stage design uses a mixture of specially chosen discrete low-noise transistors in combination with ICs. This enables us to design mic preamps with exceptional noise performance and a superior gain range.

And just because you’re working out of your home studio or on the road, doesn’t mean you should compromise on the quality of your audio interface. With SSL 2+ we’ve chosen to use the same industry-grade parts as found in our larger consoles and I/O products, delivering the same kind of quality you’d expect from a large SSL-equipped studio, into your personal workspace.

    Quality product, easy to setup and get started. Haven't had the chance to use the 4K button yet but for headphone music making it definitely does everything I need. It feels high quality and a nice weight and all the knobs feel nice and not flimsy.

  • JC


    Great product.

  • Tom


    Amazing interface for the price.

  • Dave P


    Really enjoying using this product mainly with my iOS and laptop setup so far, needed a powered USB hub to use with iOS devices but that was expected, really good support pages on SSL's website and loads of useful bundled software (though a lite version of ableton 11 rather than 10 would have been the icing on the cake) other than that the interface does everything i had hoped! Happy customer :-)

  • Russell


    excellent sound and such a great price
